Oil paint dries very slowly, Unlike acrylic paints which dry very quickly. Acrylic paint was initially created as an underpainting medium for oil painting.

It is perfectly stable to put a base of acrylic and then place oil paint over it. Linseed oil added to oil paint will extend color, increase flow and increase workability. Oil paint with added medium is called long, oil paint used directly from the tube is called short or stiff.

You place you oil paints on a wooden board called a palette the very best palettes are made of pear wood.

It is very important to understand your paints and know which colors are:

Transparent (see through) Semi Opaque (slightly see through) and opaque (not see through) getting started put as much oil paint on your brush for two strokes three maximum always end your brush stroke on the canvas.

Make sure that you use linseed oil only when you are painting with the wet on wet method or process.

Do not confuse yourself with all of the many other mediums. Wait to discover those when you are more experienced. If you can actually afford the professional paints, definitely go ahead and buy them. You will notice immediately that they are completely different from the student paints.

Always buy the best brushes that you can afford. The Da Vinci brand brushes are the best professional brushes. Buy long handle bushes. The technique is to hold near the end of the handle. When developing talent one point to consider is the ability to take risks. Just play around with your paint however first understand it, only paint at an easel and make sure to stand back from your painting all the time. Never put your expensive brushes in turps when you are working in a session. Go ahead and wipe them clean with paper towels or cloth wash out your brushes in turps or a similar solvent at the end of a session and then be sure to clean immediately with soapy water.

Preparing the canvas the foundation of you piece

It is quite essential that you put on the first underpainting or wash on your canvas. This takes away the glare of the white (which will reflect back at you, quite annoying) and the more layers of paint you get onto your canvas the better and the more professional looking your painting, the more luminous the paint ant the more the painting will sing out with color and texture.

Traditionally an earth color of a burnt umber or raw umber, raw sienna or an ochre was painted on as a good first underpainting. Sometimes it can be pretty exciting to paint on a bright red or dark blue as your first underpainting especially when you are in the habit of putting on three or four layers and seeing the underpainting come through your painting. Use a big wash brush to apply the first underpainting it you use acrylic as your underpaint it will dry quickly and get you started quicker.

How to apply oil paint in two methods

1. Wet on wet or All Prima (in one step)

2. Stage Painting or Glazing Fat over lean

Wet on wet is applied by using the paint stiff, which is directly from the tube Or thinned to the consistency of salad dressing with linseed oil the essential part of painting wet on wet is making your brushes and painting knives do the work for you.

You definitely want to have full control of your brushes and experiment with different brushes to see the marks and texture streaks that they make.

Never work with turps unless you are working with the glazing method.

Never ever stand your brushes in any turps working in your painting session.

Turps will burn the bristles and inevitably there will be some left in the brush when you start to use color.

This will make it difficult to keep control of the flow or thickness of paint. The glazing technique is a process of building up your painting in a series of layers of the thinned paint.

I found this specific method for the glazing technique with oil paint it is called fat over lean

A Lean 1st layer thinned with solvent

A Lean 2nd layer thinned with less solvent

A Lean 3rd layer thinned with less solvent

A Fat 4th layer straight from tube

A Fat 5th layer thinned with little linseed oil

A Fat 6th layer thinned with more linseed oil

It is very essential that you this process exactly follow or the layers of paint will dry at different levels and possibly ***** the paint. Granted, it is a slow method and you absolutely need some patience however the results are spectacular tonal values which are essential in painting. This glazing method gives you full control of creating tones in acrylic paint. Here there is no mystery about paint.

Remember that paint is just pigment with a binder. In the case of oil paint, it is just a pigment with a drying oil usually linseed oil is used for this. The very best professional oil paints you will find are Michael Harding and Old Holland. Windsor and Newton and some other makes are good as well just make sure they are called professional paints and not the lesser quality student paints.

One last thing, Oil Paint dries very slowly, have patience and enjoy the journey. Paint on.



Tips on Oil Painting – Solvents Mediums and Varnishes

Remi Engels, Ph.D. asked:


If you paint with oils you will need a solvent to clean your brushes and thin your paints. Of course, if you paint with water soluble oils then your solvent will be water.

Turpentine is a standard solvent used to thin ordinary oil paints. You can purchase turpentine in any art supply store or hardware store. In some cases, the kind of turpentine you buy in a hardware store may be fresher because of the shorter turnaround time.

Some artists work with mineral spirits. These are also available in hardware stores. To save money, buy the largest available quantity and use a smaller container when you do your actual painting.

Tube oil paint (i.e., oil paint directly from the tube) can be difficult to manipulate. Some colors are stiffer than others and may be hard to evenly distribute over your canvas. To solve this problem, artists often need to mix their tube paints with a so-called painting medium.

A painting medium is a liquid solution that makes the oil paint smoother and easier to manipulate. Adding any one of a number of different painting mediums changes the consistency of the paint. Some mediums are meant to make the paint thinner for glazing and others are meant to make the paint thicker for impasto painting. There are also mediums to shorten or lengthen the drying.

 

The most basic medium is regular turpentine. Adding a little turpentine thins oils paint. Another frequently used medium is linseed oil, which makes the paint more fluid but, over time, it also tends to yellow the paint. The most commonly used medium is a combination of turpentine and linseed oil, sometimes with the addition of a little damar varnish.

Begin by experimenting with a half-and-half mixture of turpentine and linseed oil. Because linseed oil slows down the drying process, you may want to increase the proportion of turpentine. A good mixture is three parts of turpentine to one part of linseed oil.

Once you find the medium you like, mix a batch and store it in a tightly sealed jar. As you paint, dip your brush into the medium, then add a little paint, then mix them together on your palette (mixing surface).

Preliminary compositions can be drawn on your canvas with a so-called thin turp wash, i.e., a little bit of paint with a lot of turpentine. A turp wash evaporates very quickly, so you can quickly paint over them.

In general, the more turpentine you use the matter the finish will be and the more linseed oil you use the glossier it will be. If you like robust, permanently visible brushstrokes, you may want to use less medium. Dry brush is one technique where you do not add any medium at all.

Special painting mediums are also available that change the oil paint in different ways. The most common are those that shorten or lengthen the drying time of the oil paint. Check your art supply store or the Internet to see the available types of mediums. All medium bottles will show instructions on how best to use the particular medium.

Oil paintings must be varnished to protect them from undesirable elements such as dirt and toxins. Varnish is a clear solution made from a resin and turpentine or some other solvent.

In art-supply stores you will see two major types, retouching varnish and picture varnish. Depending on the paint layer thickness, it can take six months or more for an oil painting to dry. In the meantime, the surface of the painting needs to be protected with a coat of retouching varnish. After the varnish is applied, the turpentine evaporates, and leaving a thin protective coat. You can apply retouching varnish as soon as the paint feels dry to the touch.

 

Picture varnish contains more resin than retouching varnish. It should be applied about six months after you complete a painting. If you paint with impasto-like brushstrokes, you may have to wait as long as a year before applying the final coat.

 

Both types of varnish are applied in the same manner. Using a broad, flat nylon brush, apply the varnish evenly using horizontal strokes. You can also use retouching varnish to brighten dry dull patches in your painting.



To Clean an Oil Painting- Follow These Easy Instructions

Kathryn Dawson asked:


Compared to other mediums of painting such as water colours or acrylic or charcoal and so on, oil paintings have always been a favourite medium for artists as well as art lovers. However, the oil medium has its own peculiarities particularly with respect to how it weathers the passage of time.

For an oil painting to retain its original shine and form, the artist or the collector needs to maintain it carefully. Particularly if you are an art lover or collector who owns one or several oil paintings, the best way to maintain the paintings is to get some professional help to clean or refurbish your valuable collection.

But hiring a professional can be quite expensive and time consuming. If you follow a few simple steps carefully, you can effectively clean the oil paintings on your own. Here are some easy to follow steps, guidelines and directions on how to clean oil paintings yourself.

1. Use soft brushes

To maintain the quality of the oil painting always give stress on using very soft brushes to remove dirt. While dusting an oil painting make sure not to flex the canvas or to remove the oil paints by bumping the painting. Avoid dusting the loose flaking paint as while doing so you might damage the paint completely.

2. Use gentle solvent

If the original oil painting is in good shape but the varnish is quite aged, you can apply a gentle solvent known as conservation liquid for cleaning it. Use the solvent with a cotton swab and apply it on the paint very carefully. To be on the safer side, it is advisable to test the reaction of the solvent by applying it on just one corner before trying it on the whole canvas. Use the solvent in an area with sufficient ventilation.

3. Clean the back of the painting

You must also pay attention to the back of the painting and clean it regularly by brushing or vacuuming. But before cleaning the back, remove the painting from its frame and place it on a clean surface. You can remove the dirt by vacuuming it with the help of a small nozzle with a brush attachment. If possible you can also use a cover on the back of the painting to prevent the accumulation of dust behind the painting.

4. Stop bacterial growth

For a new oil painting, chances are high for build-up of dirt, smoke, and bacterial or any fungal growth. After making sure that the paint is not showing any cracks or flakes, cautiously dust the surface with a baby toothbrush or shaving cream brush. Also make sure that the painting is not accumulating moisture in any form as it would totally damage the painting in the long run.

5. Remove the surface dirt

If the dirt accumulated on the front surface of the painting cannot be removed by dusting, you can use cotton pads dampened with distilled water. The cotton pad must be lightly rolled on the surface to remove dirt.

6.   Avoid extra decoration

Additional decorations such as placing live plants around paintings must be avoided at any cost as pests and insects can stain the oil painting and damage the frame.

7.    Take help of experts

Take the help of qualified experts to clean or refurbish any oil painting which is covered in dust or has completely yellowed varnish. Such paintings cannot be cleaned properly by novices. If you try to make such a painting look brighter with some handy tips, you might damage it completely.

Follow these steps and enjoy the charm of an original oil painting for generations to come.
